4 This invention relates to improvements in submarines, and particularly to a safety device for 'establishing direct communication i, between persons outside of, and persons with- 5 ing a submerged submarine.

' TheA main object of the invention is to providesimple and practical means through which persons held captive in a submerged y. submarine may be provided with air and food, telephone and other communication.

Another object is to provide a device which persons outside of the submarine may operate to establish direct communication with the interior of the submerged submarine without the assistance of those held captive within the ship.

Another object is to establish the desired communication without injury to the submarine and without danger to its occupants. In the drawing:

Fig. 1 is a vertical sectional view of the deck or wall of a submarine embodying the built-in portion of my invention.

. Fig. 2 is a view similar to Fig. 1 and showing, in additon, the communcation-establishing device (in elevation) in partial engagement with the built-in part of the structure.

Fig. 3 is a view similar to Fig. 2, showing the parts completely assembled. 89 Fig. 4 is a section taken on the line 4 4 of In that embodiment of my invention shown in the drawing, the deck or wall of a sul- Y marine is indicated at 10, the outer surface at 11 and the inner surface 12. The wall 10 is provided with a circular aperture entending therethrough and in this aperture is ted the tube 13 which is long enough to entend from the surface 11 to the surface 12. rlhe w tube 13 is internally screw threaded at each end as indicated at 14 and 15, respectively. At the outer end of the tube, engaging the threads 14, is a screw threaded plug 18 which may be removed from the tube 13 by any suitable tool engaging the recess 17 in the outer surface of the plug 16. At the opposite, inner end of the tube 13, engaging the threads 15, is a plug 18 formed with an inwardly directed tongue 19. recess 2O is provided on that surface opposite the tongue 19.

Normally the plugs 16 and 18 are in the position shown in Fig. 1, completely closing the passageway defined by the tube 13 extending through the submarine wall 10.

In the event of accident, communication may be directly established with the interior of a submerged submarine by the means about to be described. ln Figs. 2 and 3 is shown the'tool which cooperates with the screw threaded portion 27. Below the screw threaded portion 27 is a hollow tubular body e 28 having its walls cut away at opposite sides, as indicated at 29, to form a socket with downwardly extending vspaced apart arms 30, 31. The combined length of the body 28, arms 30, 31 and screw threaded portion 27 is slightly less than the length of the tube 13.

To use the communication-establishing tool a diver will rst re-move the plug 16 from the tube 13. 'This allows only a limited amount of water to enter the tube but no water will pass into the submarine because of the presence of the plug 18 in the inner end of the tube 13. The socket 28 is then inserted into the tube 13 as shown in Fig. 2, with the edges 32 and 33 of the arms 30, 31, respectively, contacting with the tongue 19 of the plug 18. By turning the hexagonal collar 2Gthe body members 21, 28 will be rotated and the screw threads 27 will engage'the threadsv 14 at the outer end of the tube 13. Simultaneously, due to the engagement of the arms 30, 31 with the tongue 19, the rotation of the tool will unscrew the plug 18 and disengage the threaded portion of the plug from the threads 15. By the time the threads 27 have fully engaged the threads 14 of the tube 13 and a water tight connection has been perfected between the flange 34 of the tool and the outer end of the tube 13, as shown in Fig. 3, the plug 18 will have dropped into the submarine and communication will have been established between the exterior and the interior of the submarine.

Air and food may be passed through the conduit 24, tubular bodies 21 and 28 into the submarine. Obviously the form and size ofthe conduit 24,tube 13 and communicationestablishing tool may be altered to accommodate the materials intended to be passed therethrough. Any desired number of the Safety devices may be applied to the submarine decli and walls. If the deck or wall of the submarine is relatively thin, the tube 13 may protrude into the interior of the submarine beyond the inner surface of the deck or wall. Another' modilication which, obviously, may be made is the elimination of the outer plug 16 and the lengthening, if desired, of the plug 18.

Changes may be made in details of construction without departing from the scope of my invention and I do not intend to be limited to the exact form shown and described except as set forth in the appended claims.

I claim as my invention:

1. In a Vsubmarine having an opening through its wall, a tubular wall fitted into the opening and extending from the inner to the outer surface of the submarine, the tubular wall being internally screw threaded adjacent each end and non-threaded between said ends, a screw threaded plug engaging the screw threads of the tubular wall adjacent the inner surface of the submarine, a hollow rotatable body adapted to be inserted within the tubular wall, means on the end of the hollow body for engaging the inner plug to unscrew the same and remove it from the tubular wall, screw threads located on the outside of the hollow rotatable body at a distance from its end for engaging the screw threads of the tubular wall near the outer surface of the submarine simultaneously with the removal of the plug, a nut integral with the rotatable body of greater diameter than the rotatable body, located outwardly of said screw threaded portion, and a swivel coupling on the outer' end of the rotatable body, the length of the rotatable body including the plug engaging means and the screw threaded portion being slightly less than the length of the tubular wall.

2. In a submarine having an opening through its wall, a tubular wall fitted into the opening and extending from the inner to the outer surface of the submarine, the tubular wall being internally screw threaded adjacent each end and non-threaded between said ends, a screw threaded plug engaging the screw threads of the tubular wall adjacent the inner surface of the submarine, a temporary closure plug engaging the screw threads of the tubular wall adjacent the outer surface of the submarine, a hollow rotatable body adapted to be inserted within the tubular wall after removal of the temporary closure plug, means on the end of the hollow body for engaging the inner lug to unscrew the same and remove it from t e tubular wall, screw threads located on the outside of the hollow rotatable body at a distance from its end for engaging the screw threads of the tubular wall near the outer surface of the submarine simultaneously with the removal of the plug, a nut integral with the rotatable body of greater diameter than the rotatable body, located outwardly of said screw threaded portion, and a swivel coupling on the outer end of the rotatable body, the length of the rotatable body including the plug engaging means and the screw threaded ortion being slightly less than the length o? the tubular wall.

In testimony, that I, claim the foregoing as my invention, I aix my signature, this 26th day of August, 1930.
